TRANSOM ADJUSTER AND LOCK.

SPECIFICATION forming part of Letters Patent No. 622,363, dated April 4,1899. Application filed April 21,1898. Serial No. 678,324. (No model.)

To all whom it may concern.-

Be it known that I, NATHAN HOSKINS, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements in TransomAdjusters and Locks; and I do hereby declare the fol The preferred formof my invention is illus trated in the accompanying drawings, where-y inlike characters indicate like parts throughout the several views.-

Figure 1 is a perspective view showing my improved transom adjuster andlock applied in working position to a transom and doorframe. Figs. 2 and3 are detail views, in side elevation, showing the lock portion of thetransom-adjuster removed from the transom and door-frame. Figs. 4 and 5are views in side elevation showing the lock portion of the transom-adjuster applied in working position to a transom and door-frame, butillustrating different positions of the parts. Fig. 6 is a transversevertical section taken approximately on the line 00 00 of Fig. 1; andFig. 7 is a detail view, partly in side elevation and partly in section,showing the friction-clamp for securing the transom-adjusting rod in itsdifierent positions.

1 indicates a door-frame, and 2 indicates a transom hinged to theopening in the upper portion of the same in the ordinary manner.

3 indicates a lock plate or lug which, as shown, 7

is secured to the inner edge or face of the doorframe 1, adjacent to theupper free end of the transom, by means of screws 4. In its upper edgethis plate or lug 3 is provided with a lock-notch 5.

6 indicates a bracket which is secured to one edge of the transom 2 bymeans of screws 7 or otherwise. Alock-lever 8, havingalockflange 9 whichis engageable with the locknotch 5, is pivoted to the bracket 6 at 10.

11 indicates an elbow or L-shaped slotwhich is cut in the body of thebracket 6. A detent 12 is pivoted to the inner end of the lock-lever 8and is provided at its depending free end with a projecting pin or stud13, that works in the elbow-slot 11. To the end of the pin or stud 13which projects. through the slot 11 is pivoted a small plunger 14, theouter end of which works through a perforated keeper 15 on the bracket6. A spring 16 on the plunger 14 puts the detent 12 under yieldingstrain to swing inward or toward the lock plate or lug 3. A lip orprojection 17 on the free end of said detent 12 is adapted forengagement with the outer edge of the lock plate or lug 3 when thetransom is closed, as shown in Figs. 1, 2, and 3. When the free end ofthe lock-lever 8 is drawn downward and the transom is partially open,the spring 16 will throw the stud 13 into the horizontal andinwardly-extended portion of the slot 11.

18 indicates a guide-rod which is secured to one side of the door-frame1 in a' vertical position, as shown, by means of end brackets 19, thatare screwed or otherwise secured to said case. 20 indicates avertically-movable rod, the upper end of which is rigidly secured to orintegrally formed with a sliding head 21, that works freely on theguide-rod 18. A connecting-rod 22 is pivoted at its lower end to thesliding head 21 and at its upper end to the freeor outer end of thelock-lever S.

The lower end of the rod 20 works through a pair of cooperating U shapedclamps 23 and 24, which are perforated, respectively, at 25 and 26 topass said rod 20. The clamp 23 is provided with feet portions 27, whichare rigidly secured by screws or otherwise to the door-case 1. Thescrew-threaded stem 28 of a knurled head 29 works through the crown ofthe clamp 24 and is swiveled to a block 30, that bears against the crownof the clamp 23. As is evident, by turning the head 29 in its stem 28the cooperating clamps 23 will be caused to tightly bite upon the rod 20and securely hold the same wherever set.

The operation of the device as an entirety is substantially as follows:When the transom is opened or partially opened, as shown in Fig. 4, thepin 13 of the detent 12 will be held in the horizontal portion of theslot 11, and the bracket 6 and lock-lever 8 will be thereby rigidly heldagainst pivotal move* ment one with respect to the other. Under theseconditions it is evident that the vertical movement of the rod 20 willpositively move the transom 2. Vhen, however, the transom has beenclosed or nearly closed, as shown in Figs. 3 and 6, the lipor-projection 17 on the free end of the detent 12 will, by itsengagement with the lock plate or lug 3, force the pin 17 in line withthe vertical portion of the slot 11, so that the further upward movementof the rod 20 and connecting-link 22 will throw the lock-flange 9 of thelock-lever 8 into engagement with the lock-notch 5 of the lockplate 3.\Vhen this has been accomplished, the transom will be positively lockeddirectly to the door-frame. lVhen the transom is opened, the action willbe just the reverse from that just described-that is, the downwardmovement of the rod 20 and connection 2-2 will move the lock-flange 9out of engagement with the lock-notch 5 and the pin or stud 13 will beraised into line with the horizontal portion of the slot 11, and nextthe transom will be moved so as to permit said stud 13 to be thrown intothe horizontal portion of the slot 11 under the action of the spring 16,thereby again rigidly connecting the loek-lever S to the bracket 6.Preferably the depending end of the rod 20 is provided with alaterally-projected finger-piece 31, by means of which the rod may bemore readily moved. This feature of positively locking the transom tothe case is of great importance, and I consider the same broadly new.\Vit-hout such a lock the transom may be forced open simply by bendingsome of the adjust ingrodsa matter very easily accomplished; but with myimproved lock force applied to push the transom open will be takenentirely by the lock and will not be applied to the adj listing-rods. Itwill be noted that the connecting-rod 22 runs diagonally from thesliding head 21 to the free end of the lock-lever 8, thereby removingthe necessity of offsetting the connected parts. Y

From the foregoing description and state ments made it will beunderstood that I do not limit myself to the details of constructionspecifically described and illustrated, but, on the contrary, myinvention is capable 'of a large range of modification.

\Vhat I claim, and desire to secure by Letters Patent of the UnitedStates, is as follows:

1. An adjuster for a transom or similar device, comprising a locknormally held as a rigid section of said adjuster, and a trip operatingto release said lock and render the same operative under the finalclosing movement of the transom, substantially as dcscribed.

2. In an adjuster for a transom or similar device, the combination witha latch plate or lug secu rable to the fixed support, of a bracketsecurable to the transom, a lock-lever pivoted to said bracket andengageable with said lock plate or lug, a detent normally holding saidlock-lever rigid, which detent is rendered inactive to hold saidlock-lever, when the transom is closed, and a transom-adjustingconnection attached to said locking-lever, substantially as described.

3. In an adjuster for a transom or similar device, the combination withthe notched latch plate or lug 3, 5, securable to the fixed support, ofthe bracket 6 securable to the transom and having the slot 11, thelock-lever 8 pivoted to said bracket 6 and provided with the flange 9engageable with said notch.

5, the spring-pressed detent 12 pivoted to said lock-lever 8 andrendered inactive when the transom is closed, and a transom-operatingrod or connection attached to the free end of said lock-lever 8, saidparts operating substantially as described.

In testimony whereof I aifix my signature in presence of two witnesses.-
